//number 数値
let num: number = 1;

//string 文字列
let str: string = "A";

//Array 配列
let Arr1: Array = [0, 1, 2];
let Arr2: number[] = [0, 1, 2];

//tuple 1つの配列の中に型の違う値を格納
let tuple: [number, string] = [0, "A"];

//any
let any1: any = false;

//void 返却値のない関数
const funcA = (): void => {
const test = "TEST";
};

//null
let null1: null = null;

//undefined
let undefined1:undefined = undefined;

//object オブジェクト型
let obj1: object = {};
let obj2: { id: number, name: string } = { id: 1, name: "NAME"};
